FSM advantages?

[Inswitch Solutions - Erlang Evaluation]

Martin,

Thank you I've found the  function
sync_send_event(FsmRef, Event, Timeout) -> Reply
which does exactly what I need.

I just only need to know what's the reply term when the Timeout ocurr?


Regards,

The fsm is fine for an automaton with time constraints. gen_fsm supports
user defined states and user defined transitions between those states.
Any state can be augmented with a timeout. A programmer can specify the
behavior of the fsm when such a timeout occurs.

Cheers,
Martin
